My 98 blazer (130k)recently started showing code p0740 tcc circuit malfunction..
The truck runs fine (except for the water pump I just blew) this is a tranny solenoid code. but my tranny seems to be shifting ok..
Is the solenoid easy and cheap enough to replace myself? I am trying to make up my mind if its time to start thinking of trading this blazer in on something with less miles or to fix it up and keep on trucking..
The first is a trans control system malfunction and the 2nd code(0740) is tcc circuit malfunction- but what exactly do these codes mean? and the o2 sensor needs to be replaced, it said bank 1 sensor 1- does that mean the one BEFORE the catalytic converter?
View 4 RepliesI have 94 SE camry with the 3.0L V6 1MZ-FE engine and has individual coil packs. I'm getting a P1300 Igniter Circuit Malfunction. I have checked it out per the procedures EG2.pdf. I'm down to step 8 and the voltages are little different between the 6 points. started checking out the ground at the ECM per IN36 instructions. it appears that from pin #27 & 28 are not grounded to the ECU case.
View 5 RepliesSC430 came up with the check engine light, showing a "Oxygen Heater Circuit Malfunction", code P0155 (bank 2, sensor 1). Searching, I found out this is the oxygen sensor in the passenger side exhaust manifold.
My car is high mileage (over 130K), it's hard to justify purchasing a $230 sensor and paying for installation. My only goal is to keep the check engine light from turning on and passing state inspection/emission (the check engine light will prevent passing inspection/emission in my state).
After about 6 months I finally got the alternator replaced in the Tribute. I totally forgot about the CEL that was on for EGR Circuit. I've found a couple of pages ( OBD-II Trouble Code: P0403 Exhaust Gas Recirculation Circuit Malfunction ) that explain how to diagnose the issue but I was wondering if any other route for something that may be more common than another thing.

DTC P0705
Description : transmission range sensor circuit malfunction
State : History
I have done some google search on the above diagnostic trouble code P0705 and as i understood , it indicates that the Engine Control Module (ECM) has received an input error from the Transmission Range Sensor (TRS).
Since the check engine light illuminated two times (two separate occasion) then it turns off now; the ECM is actually receiving input signal from the TRS.
So that leads me to think that the TRS is actually working but the problem might be one of the following two:
1- Open or short in the TRS circuit?
2- Dirty transmission fluid.
What do you think the steps i should do first of all ? how would i check the transmission fluid since my vehicle has no transmission fluid dipstick. My driving condition would fall into "severe" category and it reached 60,000 miles now ...
CEL/OBDII code P0141 - O2 Sensor Heater Circuit Malfunction
So I just bought this car 64k well maintained but cant get rid of the check engine light. Replaced downstream O2 sensor with no luck. As soon as I get home I'll check voltage @ connector. Lets test the O2 sensor connection and test the pins to make sure there is no break in the wires.
Just got a P1135 Code on the 1MZ-FE 2002 Camry.
My code reader pulls it up as (no typo below) : AirCFuel Sensor Heater Circuit Response Malfunction.
So I know it's a bad Air/Fuel sensor. Which one though? I replaced the rear sensor by the firewall about 6 months ago which fixed the check engine code (I don't remember the code). Would it make sense that the front one failed now or the back one failed again? Most of my research points me to a bad rear sensor however a lot of people also report that a code reader would report the sensor as "Bank 1 Sensor 1".
The rear sensor was replaced with a Denso 234-9042 Sensor.
I would play the replace and test game... however inspection is due within the month and after resetting the code, it usually takes about 50 miles to return. Being in college, 50 miles takes about 2 weeks.
I have a 2007 ES350 with 90k miles. Purchased in August. I had ignition coil go out and decided to change them all and the spark plugs. When changing cylinder 5's coil and plug, I tried to push the wiring harness out of the way to remove the coil. Result, I moved the wiring harness too far and disconnected the 3 wires (black, yellow and red) that were connected to the cam position sensor connector. (I should've just removed the sensor SMH) I disassembled the connector, got it down the internal pins, soldered the pins to the wires, placed the pins back in the connector and reassembled it with the wires in the order that they appeared to originally be.
Plugged it back in and put everything back in place. Started the car and code P0352 was cleared but replaced with code P0365 Camshaft Position Sensor B - Bank 1 Circuit Malfunction. I'm thinking, either I put that pins back in the wrong order or one of the wires isn't properly soldered in. Either way, I ordered another connector and it should be here tomorrow. I need Either a wiring diagram or a picture of the camshaft position sensor closest to cylinder 5 connected with the wires in the proper order .
The 2005 Avalon has 48K miles and it's been running well without any issues, until today.
Driving in city traffic, max speed is about 30 ml/h, The "Check Engine" light and the "VSC (Vehicle Slip Control) Off" lights came on. I did stop the engine, restarted after couple of minutes and the same lights stayed on. The car ran just fine, no noticeable difference in performance.
With the OBDCOM reader, the Avalon has this code:
P0351 232
P0351 Ignition coil A primary/secondary circuit malfunction
That seems to indicate a malfunction for cylinder A, or #1, ignition coil that has nothing to do with the "VSC" AFAIK. Is this a misread by OBDCOM reader, or the Avalon is confused?
The code had been reset via the OBDCOM reader, the car runs fine, neither of the lights come on now. Should I do something about coil A, or just wait until the code comes back?
I have a 2003 Santa Fe, V4, 2.4L.
So the other day, my CEL and I got it scanned: p0320, or "Ignition/Distributor Engine Speed Input Circuit Malfunction."
It was accompanied with two symptoms:
1. The car will sometimes sputter on startup, and the tachometer will be zeroed out. I have to turn the car off and turn it back on, and it will start normally, albeit with a bit of a misfire on idle.
2. The car will sometimes die while at a stop. Just like the first symptom, if I turn the car off and turn it back on, it will work normally.
I looked on here, and it seemed like everyone solved a p0320 by replacing the Ignition Failure Sensor. So that's exactly what I did. But nothing changed; I still have the symptoms, and the CEL came back on and is still reading p0320.
What should be my next step? Could it be faulty wires that give power to the Ignition Failure Sensor?
I have a 1999 Ford Explorer with the V-6 SOHC that is stuttering and stalling when I try to accelerate. A very slight acceleration will get the vehicle moving, but anything coming close to normal gas pedal pressure causes immediate stuttering and/or stalling. Check Engine light came on when problem started yesterday.
Where is the EVAP System Canister Vent Solenoid? I bought a code reader after beating my head against the truck all afternoon and got code "P1451 EVAP System Canister Vent Solenoid Circuit Malfunction". My Haynes book says on the left side frame rail... can't find anything along there that looks like it (based on picture from Rock Auto for replacement part) and found some people online talking about it being in the engine compartment on the passenger side...
Just crawled all over the truck and I think I found the charcoal canister, but couldn't trace it back to the vent solenoid... There was something right next to the canister, but again, it looked nothing like the replacement part listed on Rock Auto...
Yesterday driving to work felt the engine missing, on the way home got a CEL pulled the code when I got home it was P0302, so I started with the easy and put a new coil pack, same issue, so I prayed and pulled the plug (it didn't break). Put a new plug and a second new coil pack (just to be sure, and yes I keep extras dang 5.4). cleared codes and started it this time got P0202 Ford - Injector Circuit Malfunction Cylinder 2, so I checked Ohms on #2 and it was 12.6, #1, 3, 5,6 all have 13 Ohms, didn't check #4, 7, or 8 because my big hands and the probes on my multi meter. Checked the wires on all of them and have 12 volts with key on, not running. I read another check to put blk in pin and red on pos batt terminal, and that it was supposed to go 12 to 0 off and on with engine running, All of mine went up to 14 volts and stayed no switching. Is there something I am missing to check before replacing the injector on #2?
View 6 RepliesI'm not too knowledgeable about wiring and electrical systems. I'm getting a P1451 code (EVAP Control System Canister Vent Solenoid Circuit Malfunction) on my 99 4.2. I've read that it could be a bad solenoid, bad wiring, or a blown fuse. So far I've;
- checked (and changed) the related fuse
- checked the wiring for damage at the connector
- checked voltage at the connector (12 volts)
- checked the resistance at the solenoid (around 60 ohms)
- actuated the solenoid with a 9V battery (can hear it opening and closing)
I haven't had a chance to check the wiring all the way back up the frame to yet, but I noticed that the ground at the trailer wiring harness has broken off the frame. Would this potentially cause a fault in the upstream wiring? I'm going to slap a new connector on and bolt it back down anyway, but as it's Labour (Labor) Day I'll have to wait for the stores to be open tomorrow.
I just bought a '98 Ranger 2.5l 2wd. After driving it for a week or so I got a P1405 Code. After a quick google search I got :
P1405 Ford - DPFE Sensor Circuit Upstream Hose
Possible Causes: - Faulty Differential Pressure Feedback Electronic (DPFE) sensor (EGR pressure sensor)
- Plugged or damaged EGR tube
- Differential Pressure Feedback Electronic (DPFE) sensor harness is open or shorted
- Differential Pressure Feedback Electronic (DPFE) sensor circuit poor electrical connection
Now, I have done my research between forums and youtube and have found this EGR system to be quite. I've gone ahead and replaced my DPEF. I took an air hose and blew out all the small lines coming into the DPEF. I still have the engine light. My next move is to get a volt meter and see if I'm getting power to the sensor.
My question is about this particular code and is it possible I need to look farther into this EGR system (EGR Valve, EGR Hose, etc.)
I bought late 98 F-250, 5.4 G, 4WD. OHad to replace the steering flange because they messed up the ignition cylinder and flange. Truck didn't run for 4 years. 249K miles, no history available. Got the engine running, no DTCs. D, 3, 2, 1 barely moved the truck forward but, R hauled butt in reverse. Checked transmission fluid it was good and clean.
Came back to it a few days later it threw a P0720 (output speed sensor circuit) and I have no reverse, park feels like it wants to move, R is neutral, N is forward, D is forward, 3 is forward, 2 is forward, 1 is forward. The N is full drive. I cleared the P0720 code after it came up and it has not returned. The instrument gauges work but the odometer display is intermittent. Linkage? Fluid? Sensor? Wires?
while scraping ice off the windshield this morning with the car warming up, it started to choke, engine light came on. Used my OBD reader and found only one code, that being p0740. Cleared the code and all was fine after that, it drives the same way it always has and nothing feels different, revs are the same shifts gears the same. I know it had something to do with the torque converter clutch.
View 4 RepliesMy mother has the code to the radio, but when she was entering it she did it wrong. It now says "2 SAFE" or something similar and won't allow any other info entry. We even disconnected the power again and it still says the same thing. How do yo uget it baack to the point of allowing the 4 digit code to be entered?
View 2 RepliesI have a 98 camry with code p0755 - shift solenoid valve#2 malfunction.-What are some of the most common causes. How to test it ,the issues that cause this and what to do also after replacing it if bad? Also are these to be replaced in pairs with both 1st -2nd shift and 2nd to 3rd shift .
If I have high miles on it will adding the 2 -3 quarts of new fluid give me issues as to mixing with the old and part breaking up in transmission(I've heard a lot happens when u replace very old fluid with new or flush it fully)..will be replacing filter also but not the rest of fluid still in transmission at this time. Looking for a link a pic. of the exact location on transmission inside pan .of it(looks similar to other shift solenoid near it )...
The engine sometimes has misfiring, and the VCDS reports "Injector Circuit Malfunction Cylinder 7, sporadically". I changed the spark plug, the injector and the ignition coil. So the problem remained and after about 600-800kms the fault came back. Now I moved a little bit the cables of the injector plug and I noticed that the problem is solved, until a few hundred kms were driven. The cyl. 7 is near front side and I could move the cables to the injector plug under the intake manifold.
Now I know, that the problem is the plug of injector (see pics)....
My question.... I bought the plug but it is not the complete like on the pics, it's only the middle part where the cables go in. It has not this sponge-like thing which is in the whole in which goes in the cable. The grey thing which locks the plug is also not in the new plug. Maybe if I have to exchange this small parts on the new plug? I can't imagine how to change the plug, do I have to cut the cables and put them in the new plug. What kind of attachement do the cables have in this plastic plug?
I have a 2010 Ford Escape. The engine light came on about 10 days ago. I ordered a OBD which arrived the day that the engine light went out (two days ago...) Anyway, the OBD showed a P1490, which, according to google means Secondary Air Relief Solenoid Circuit Malfunction.
